You work for a company that makes cell phones and have been made project manager for the design of a new cell phone. Your

supervisors have already scoped the project, so you hove a list showing the work breakdown structure, and this includes major project

activities. You must plan the project schedule and calculate project duration. Your boss wants the schedule on his desk tomorrow

morning!

You have been given the information in Exhibit $4\mathrm{.}13.$ It includes all the activities required in the project and the duration of each

octivity. Also, dependencies between the activities hove been identified. Remember that the preceding octivity must be fully

completed before work on the following activity can be started.

Your project is divided into five major subprojects. Subproject $"P"$ involves developing specifications for the new cell phone. Here,

decisions related to such things as battery life, size of the phone, and features need to be made. These details are based on how a

customer uses the cell phone. These user specifications are redefined in terms that have meaning to the subcontractors that will

actually make the new cell phone in subproject $"S"$ supplier specifications. These involve engineering details for how the product will

perform.

The individual components that make up the product are the focus of subproject $"$D$."$ Subproject "I" brings all the components

together, and $0$ working prototype is built and tested.

Finally, in subproject $"V,"$ suppliers are selected and contracts are negotisted.
